The Horn of Africa Is Drying – in Sync with Climate Change

The Horn of Africa has become progressively drier over the past century, and it continues to dry at a rate that is both unusual in the context of the past 2,000 years and is in step with human-influenced warming, according to a new study from Lamont's Peter deMenocal. The findings run counter to earlier projections and hold a warning for one of the most geopolitically unstable regions in the world. 

Powerful Winds Strip Far More Snow from Antarctica than Scientists Knew 

Powerful katabatic winds are stripping vast amounts of snow from steep slopes in East Antarctica, vaporizing as much as 200 years of snow accumulation in places. The discovery by Lamont's Indrani Das could boost estimates of the continent's contribution to sea level rise and scientists' ability to model future changes in the region.

Measuring the Suntan on a Rock and Other Innovative Ways to Map Ice Sheets through History

Nicolás Young, just named the winner of a 2015 Blavatnik Award for post-doctoral scientists, is developing two innovative methods for tracking historic changes in the Greenland ice sheet, particularly during periods when the planet was warmer than today. One method starts with the color of lakes as seen from space; the other, Young dubs “measuring the suntan on a rock.”

Giving Day Is October 21: Be Part of Our Future
